Hi all, I need a little help here; this is going to sound weird but bear with me, ok? I'm not a sound engineer by any means...I am a paranormal investigator, and I'm trying to find out what omnidirectional mic would be best paired with a Zoom H6 portable recorder to capture low frequency voices. If anyone would like me to send a clip to see what I'm talking about, hit me up. I need to eliminate as much hiss as possible. Thanks in advance.
